An unidentified Islamic Group leader speaks after a mass "standing prayer" organized by Islamic Groups to honour al-Qaeda leader Osama bin Laden, who was shot dead in Pakistan, in Khartoum May 3, 2011. Around 1,000 people on Tuesday gathered in the centre of Khartoum to praise bin Laden, chanting "Death to America". A radical Islamist party had called for the mass prayer to honour the mastermind of the September 11, 2001 plane attacks in the United States who was killed in a U.S. operation in Pakistan.
